Evolution and development of boys’ social behavior

An evolutionary analysis of the dynamics of one-on-one and coalitional male–male competition provides a theoretical frame for conceptualizing the evolved functions and proximate developmental forms of the social behavior of boys, and for appreciating why the behavior of boys differs from that of girls. We propose the accompanying selection pressures favored the evolution of motivational and behavioral dispositions in boys and men that facilitate the development and maintenance of large, competitive coalitions and result in the formation of within-coalition dominance hierarchies. Empirical research on boys’ social development is reviewed using this frame and implications for interpreting boys’ social behavior are explored.     

Judging toy breakers: Gender stereotypes have devious effects on children

Second-grade children listened to short stories about male or female children who accidentally broke neutral and sex-appropriate or opposite-sex toys. Children then rated the severity of punishment due to each toy breaker and provided justifications for their ratings. The justifications were coded for citing intentionality (or lack thereof) and toy ownership (or lack thereof). No differences were found between boys and girls in the punishment severity ratings of targets of either gender who broke neutral toys. In the punishment severity ratings of toy breakers of sex-appropriate and opposite-sex toys, gender stereotype effects were found only for girls; they suggested more severe punishment for toy breakers of opposite-sex toys, irrespective of their gender. The citation of toy ownership was found to be a significant variable in boys’ nonuse of gender stereotypes in their punishment severity ratings; with the impact of toy ownership removed, gender differences in punishment severity ratings were eliminated. Although the citation of intentions did not influence the punishment severity ratings of either boys or girls, boys referred to intentions primarily in same-sex targets. The data illustrate both the direct and the devious impact of gender stereotypes on children’s social cognitive processes.

Ten-year-old girls' and boys' body composition and peer victimization experiences: prospective associations with body satisfaction

This study examined prospective associations between 10-year-olds’ weight and height, their perception of shape and stature, frequent experiences of peer victimization, and different aspects of body esteem at age 13. Participants were 474 girls and 400 boys participating in a two-wave longitudinal questionnaire study. Main results were that whereas actually being heavier built at age 10 was associated with girls’ increments in body dissatisfaction, the mere perception of being too heavy was associated with boys’ poorer body satisfaction. Also, boys who believed that they were too short were more dissatisfied at follow-up. Whereas frequent peer victimization had long-term associations with girls’ weight-esteem, teasing targeted towards appearance was associated with boys’ more negative beliefs about what others think about their appearance. Finally, participants had become significantly more dissatisfied at age 13, suggesting that this is a time in life when both girls and boys risk becoming increasingly critical towards their appearance.     

Ethnic and sex differences in occupational stereotyping by elementary school children

As part of the formative evaluation of an educational television and print package, fourth-, fifth-, and sixth-grade public school Black, Hispanic, and Anglo children were surveyed regarding career choice and perceptions of the appropriateness of selected occupations for male and female adults and children. Responses were analyzed by ethnic membership and sex. Results indicated that in general Hispanic and Anglo girls chose more non traditional, higher-status occupations than Black girls. For boys, however, there was no clear interaction between sex and ethnic group in career choice. Girls and boys in all three ethnic groups indicated preference for careers stereotyped for their own sex, although girls—particularly Anglo girls—showed a greater tendency to cross sex-stereotyped lines. In addition, while both girls and boys in all three groups stereotyped as appropriate only for females those occupations regarded as traditionally female, traditionally male occupations were stereotyped more frequently by boys than by girls, who tended to consider them appropriate for both sexes. No differences appeared between ethnic groups in boys' responses to male and female adult occupations. In general Black girls tended to hold the most stereotypic views of job appropriateness, while Hispanic girls did not show a clear trend. Black boys tended to stereotype more than the other two groups with reference to child jobs on a boy-stereotype scale. Some differences also appeared in both boys' and girls' responses on the basis of a median split between high and low stereotypers on boy and girl child-job stereotype scales. In general, subjects who stereotyped child jobs tended also to stereotype adult occupations, suggesting a link between the child's current experience and the more remote world of adults. Implications of the findings and suggestions for future research are discussed.     

Is peer victimization related to body esteem in 10-year-old girls and boys?

Several studies show that a history of exposure to appearance-related teasing is linked to body dissatisfaction. This study extends those findings by examining the impact of bullying, and other forms of peer victimization, on different aspects of 10-year-old girls’ and boys’ body esteem. Participants were 960 Swedish 10-year-olds, 515 girls and 445 boys. Principal results show that social exclusion is related to 10-year-olds’ evaluations of their general appearance, to evaluations of their weight, and to beliefs about how others perceive their appearance. Furthermore, bullied girls have poorer body esteem in terms of beliefs of how others perceive their appearance than do bullied boys. Appearance teasing was associated with girls’ poorer body esteem in terms of general appearance and beliefs of others views of their appearance. For boys, teasing was associated with poorer body esteem on all dimensions. Thus, this study implies that a wider range of peer victimization relates to children's negative self-perceptions than was former known.     

Relations Between Suicidal Ideation,Depression, and Emotional Autonomy from Parents in Adolescence

We examined the relations between depression, emotional autonomy quality-related constructs of separation and detachment, and suicidal ideation, focusing on the unique and common contribution that depression, separation and detachment made to suicidal ideation. We also examined gender differences. 403 adolescents, 196 boys and 207 girls, completed self-report measures of depression, separation and detachment, and suicidal ideation. The data showed a significant relation between depression and suicidal ideation both for boys and girls, and between detachment and suicidal ideation only for boys. Results for boys supported an additive model such that depression and detachment each contributed unique variance to boys’ suicidal ideation, and an interactive model such that detachment contributed to exacerbate the risk of suicidal ideation when boys were already at risk because of depression. The data for girls supported an interactive, but not additive, model such that depression and detachment did not contribute independently to girls’ suicidal ideation but in a joint way.     

Gender-Role Cognition in Three-Year-Old Boys and Girls

Although the multidimensionality of gender roles has been well established, few researchers have investigated male and female roles separately. Because of the substantial differences in the ways male and female roles are portrayed in our culture, boys and girls may think and learn about these roles differently. The male role is more clearly defined, more highly valued, and more salient than the female role; thus, children's cognitions about these two roles may be expected to differ. The present study addressed the question of whether there is sex-typical variation in gender labeling, gender-role knowledge, and schematicity. Participants were 120 families; 15% were from minority ethnic groups, and 17% were single-parent families; 25% of the parents had a high school education or less. Results indicated that at 36 months of age, boys were less able to label gender and less knowledgeable about gender roles than were girls. Boys' knew more about male stereotypes than female stereotypes, whereas girls knew considerably more than boys about the female role and as much as boys about the male role. Boys and girls were found to be similar in gender schematicity. Traditionality of parental attitudes regarding child-rearing and maternal employment were not strongly related to children's gender cognition.     

The relationship between teacher ratings of kindergarten classroom skills and second-grade achievement scores: An analysis of gender differences

The Kindergarten Performance Profile, a criterion-referenced teacher rating scale, was developed by a multidisciplinary group of public school teachers, child development specialists, and evaluators. The present study analyzed the social and work skill areas of the rating scale, focusing on the relationship of classroom skills in the fall and spring of kindergarten to second-grade achievement scores. Gender differences, as well as the impact of assessing children's skills in the fall versus the spring of kindergarten were explored. Results indicated that kindergarten work skills were significantly related to California Achievement Test scores for both boys and girls; however, kindergarten social skills were related to achievement scores for girls but not boys. Teacher ratings from either the fall or the spring were predictive of achievement test scores for girls, although different girls were identified as having problems at the two time periods: whereas spring evaluations were more strongly related to boys' later achievement. The implications of these findings for assessment programs are discussed.     

Effects of real gender and labeled gender on adults' perceptions of infants.

Three experiments were conducted to discover factors mediating adults' perceptions of male and female infants. In the first experiment, college students were shown 30-s videotapes of four male and four female babies, each of whom was randomly labeled with a male or a female name. Infants labeled as male were perceived as significantly more masculine and stronger than those labeled as female. Discriminant analyses revealed that both rated masculinity and the combination of ratings on male stereotyped traits differentiated infants labeled as male or female. Analyses of real gender revealed that boys were rated as less sensitive and stronger than girls. Discriminant analyses suggested that the combination of less sensitive, more of a problem, more mature, and more playful best differentiated real males from real females. In Experiment 2, the findings of Experiment 1 were confirmed with a sample of mothers of young infants. In Experiment 3 college students' judgments of the sex of the eight babies were correctly predicted from the sensitivity ratings of these babies in Experiment 1. It appears that there is a complex of cues from which adults make judgments of infants' gender and inferences about their characteristics: Boys may appear stronger, more playful, and more of a problem, and girls seem to look more sensitive. Implications for further studies of gender labeling and for sex typing are discussed.     

Adolescent body image and psychosocial functioning

Researchers have highlighted the significance of a poor body image in the development of dysfunctional eating but have systematically investigated few other outcomes. The authors examined the relationships between different aspects of body image and psychosocial functioning. Participants were 245 boys and 173 girls from Grades 8 and 9 (M age = 13.92 years, SD = 0.69 years). Respondents completed measures of physical attractiveness, body satisfaction, body image importance, body image behaviors, appearance comparison, social physique anxiety, self-esteem, depression, anxiety, and same-sex and opposite-sex relations. Whereas girls tended to report a more negative body image than did boys, the relevance of body image to self-esteem was similar for boys and girls. Concern about others' evaluation of their bodies was especially important in understanding low female self-esteem, whereas for boys, ratings of general attractiveness most strongly predicted self-esteem. The authors found a negative body image to be unrelated to symptoms of negative affect but to be strongly associated with poor opposite-sex peer relationships, especially among boys. A negative body image also affected same-sex relations among girls.     

Temperament,classmate likability,and social perspective coordination as correlates of children's parent-rated type A behaviors

Parents of 58 boys and 62 girls from grades three through eight completed the Matthews Youth Test for Health (MYTH), a measure of Type A behavior. Normative and reliability data were similar to those obtained from teachers as reported in the literature, but a factor analysis of parents' ratings revealed four factors (Competitiveness, Irritability, Impatience, and Leadership) as opposed to the two factors (Impatience/Aggression and Competitiveness) that have been derived from teacher ratings. Boys had higher total MYTH scores than girls, but correlations with age were not significant. No grade or gender effects were obtained for any of the four MYTH factor scores. Correlates of the MYTH scores were computed separately for boys and for girls. For boys, Irritability was related to Reactivity, a Difficult Temperament, low classmate Likeability, and poor performance on two social cognitive tasks (compromising and friendship understanding). For girls, Leadership was related to Classmate Likeability and good performance on the two social cognitive tasks. For boys only, total MYTH scores were related to low Attention Span, high Reactivity, a Difficult Temperament, and low Friendship Understanding scores. Findings are related to the gender differences found in the study of both ego control and cooperation/ competition.     

Are boys better off with male and girls with female teachers? A multilevel investigation of measurement invariance and gender match in teacher–student relationship quality

Although research consistently points to poorer teacher-student relationships for boys than girls, there are no studies that take into account the effects of teacher gender and control for possible measurement non-invariance across student and teacher gender. This study addressed both issues. The sample included 649 primary school teachers (182 men) and 1493 students (685 boys). Teachers completed a slightly adapted version of the Student-Teacher Relationship Scale. The results indicated limited measurement non-invariance in teacher reports. Female teachers reported better (i.e., more close, less conflictual, and less dependent) relationships with students than male teachers. In addition, both male and female teachers reported more conflictual relationships with boys than with girls, and female teachers also reported less close relationships with boys than with girls. The findings challenge society's presumption that male teachers have better relationships with boys than women teachers.     

Preschool Children’s Beliefs about Gender Differences in Academic Skills

Evidence from different Latin American countries shows a gap in the academic achievement of girls and boys. Chilean children’s achievement is a case in point, with the gender gap being especially large for mathematics achievement. These differences can be explained partly from the viewpoint of beliefs and implicit theories. Research in this field has focused mainly on elementary and secondary students, and there is no relevant data on preschool children. This study examines Chilean kindergarten children’s beliefs about differences in the academicals skills of girls and boys. Eighty-one preschool children (34 girls, mean age 5 years and 11 months) were recruited from schools serving a middle SES population from downtown Santiago. An instrument to test children’s implicit beliefs about gender differences in academic ability was adapted from previous research. Results support the hypothesis that boys and girls at the age of 5 already hold stereotypical expectations about boys’ and girls’ academic achievement. When asked about which school subject a character liked more, was better at, and found easier, participants showed no preference between math and language when reasoning about a male character, but they indicated that a female character would find math harder, perform worse at it, and like it less than language. These responses did not differ according to the gender of the participating children. Implications of these findings are addressed and limitations and future research are discussed.     

Cognitive gender differences among Israeli children

The study investigated gender differences among 11,000 Israeli children in Grades 4–6 with respect to verbal, spatial, and mathematical ability, as measured by 12 intelligence tests. Consistent differences in score variance were found across grades for 11 of the 12 tests. In each of these tests the variance for boys exceeded that for girls by 10%–20%. With respect to mean achievement, consistent cross-grade differences were found only for mathematical ability, where boys had the edge (about 0.20 SD). These findings diverge from those of recent American studies, which found no gender differences in any of these realms. Furthermore, they differ from the results of earlier Israeli studies in that the gender gap is limited to mathematical ability, and its size is much smaller. The revealed gender gap can be partially attributed to differences in response strategy: girls were found to be more likely to skip items for which they lack an answer (i.e., to take fewer risks in guessing). This implies that the performance of girls on intelligence tests will improve if they are encouraged to dare to guess.This research was supported by the Henrietta Szold Research Institute.

Sex differences in self- and teachers' reports of self-esteem in preadolescents

The short form of the Coopersmith Self-Esteem Inventory was administered to 952 fourth- and fifth-grade children (482 males, 470 females) from 41 classes. The children's teachers completed Coopersmith's Behavior Rating Form, a measure of self-esteem-related behavior. In the self-ratings, girls were significantly lower than boys; in the teachers' ratings, girls were significantly higher. In 32 of the 41 classes, boys ranked higher in their self-ratings than in the teacher ratings; the reverse was true for girls — a highly significant difference. This pattern of findings did not occur in the 8 classes which had male teachers. Issues concerning the measurement and conceptualization of self-esteem are discussed.This research was supported by Lehigh University, using Institutional Grant funds from the National Science Foundation.

Gender Differences in Patterns of Association Between Prosocial Behavior, Personality, and Externalizing Problems

This study examines whether prosocial behavior and personality have independent or overlapping associations with adolescent externalizing problems. A total of 128 female and 103 male early adolescents (M = 13.6 years old) completed personality inventories. Prosocial behavior was assessed by peer nominations (N = 663). Composite aggression and delinquency scores were derived from maternal and self-reports. Path analyses indicated gender differences in patterns of association. For girls, links between prosocial behavior and both aggression and delinquency were fully mediated by agreeableness and partially mediated by conscientiousness. For boys, prosocial behavior, agreeableness, and conscientiousness were independently and negatively associated with aggression and delinquency. The findings suggest that personality and prosocial behavior are uniquely related to boys' behavior problems but cannot be readily disentangled when it comes to girls' behavior problems.     

Sociocultural correlates of compulsive exercise: is the environment important in fostering a compulsivity towards exercise among adolescents?

Sociocultural factors hypothesised to be influential in eating disorders were assessed for their relationship with compulsive exercise. A sample of 828 adolescent boys and girls completed measures assessing sociocultural messages to change body shape as well as pressure to be thin, and also measures of compulsive exercise and disordered eating. Results showed that the sociocultural influences differed slightly between boys and girls. Hierarchical regressions showed that, after controlling for disordered eating and BMI, messages to become more muscular and media pressure to be thin significantly predicted compulsive exercise in boys, while the same regression in girls reported only media pressure to be thin as a significant predictor of compulsive exercise. These findings demonstrate the influence of the media in boys’ and girls’ compulsive exercising, as well as highlight the influence of body shape messages to become more muscular on boys’ compulsive exercise.     

Religiosity,Prosocial Values,and Adjustment among Students in Catholic High Schools in Canada

The present study explored the facilitating function of religious commitment in the lives of adolescents. A total of 369 boys and 372 girls attending Catholic high schools in Canada completed measures of family religion, religiosity, prosocial values, social adjustment (school attitudes and family satisfaction), and personal adjustment (life satisfaction and self-esteem). There were no significant gender differences in family religion, religiosity, social adjustment or personal adjustment. However, girls endorsed prosocial values much more than did boys. Religiosity had strong positive correlations with prosocial values and lesser significant correlations with social adjustment. Religiosity had much higher correlations with prosocial values and social adjustment among boys than among girls. Structural-equation analyses of the total sample, of boys, and of girls supported a path model where family religion fosters adolescents's religiosity, religiosity fosters prosocial values, prosocial values promote social adjustment and social adjustment promotes personal adjustment.     

Gender differences in teachers’ perceptions of students’ temperament,educational competence,and teachability

Background. Student's temperament plays a significant role in teacher's perception of the student's learning style, educational competence (EC), and teachability. Hence, temperament contributes to student's academic achievement and teacher's subjective ratings of school grades. However, little is known about the effect of gender and teacher's age on this association. Aims. We examined the effect of teacher's and student's gender and teacher's age on teacher‐perceived temperament, EC, and teachability, and whether there is significant same gender or different gender association between teachers and students in this relationship. Sample. The participants were population‐based sample of 3,212 Finnish adolescents (M= 15.1 years) and 221 subject teachers. Methods. Temperament was assessed with Temperament Assessment Battery for Children – Revised and Revised Dimensions of Temperament Survey batteries and EC with three subscales covering Cognitive ability, Motivation, and Maturity. Data were analyzed with multi‐level modelling. Results. Teachers perceived boys’ temperament and EC more negatively than girls’. However, the differences between boys and girls were not as large when perceived by male teachers, as they were when perceived by female teachers. Males perceived boys more positively and more capable in EC and teachability than females. They were also stricter regarding their perceptions of girls’ traits. With increasing age, males perceived boys’ inhibition as higher and mood lower. Generally, the older the teacher, the more mature he/she perceived the student. Conclusions. Teachers’ ratings varied systematically by their gender and age, and by students’ gender. This bias may have an effect on school grades and needs be taken into consideration in teacher education.
